Would the owner of THESE:
Please come to the dungeons to retrieve them. They are hanging off the entrance to the Slytherin Common Room and no one desires to handle them for fear of catching something. If not retrieved by tomorrow, a locator spell will be cast promptly.
Hmm, or perhaps it will be cast, oh, I don't know, today during dinnertime? It should make *quite* the scene in the Great Hall.
